TALKING WATCH OR CLOCK.

SPECIFICATION forming part of Letters Patent No. 605,192, dated June '7, 1898.

Application filed August 24, 1897. Serial No. 649,288. (No model.) Patented in witzerland February 21, 1892, No. 4,918.

To all whom it mag concern:

Be it known that I, OASIMIR SIVAN, a citizen of the Republic of Switzerland, residing-at Geneva, in the canton of Geneva, Switzerland, have invented certain new and useful Im-,

provements in Talking Watchesor Clocks; and I do declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention consists of a novel construction and arrangement'of mechanism for clocks and watches, as set out in the Swiss patent granted to me February 21, 1892, and being 'serially numbered 4,918, and embodies a disk provided with a number of concentric rings,

each of which has upon its surface waves or with the outer case and record-disk removed,

showing only the mechanism for elevating the record-disk and adjusting or regulating the position of the stylus with respect to the rings on the record-disk. Fig. 3 illustrates in diagram the mechanism for winding the two spring-drums, one for operating the clock mechanism and the other for operating the mechanism designed to rotate the record-disk. Fig. erepr'esents a detached sectional view, enlarged,of the casing, carrying the stylus and record-disk, the minute-hand and pinionhand connected to its shaft for operating the stylus through the medium of a gear-wheel. Fig. 5 is a sectional view of one of the cases to said cover or casing.

or covers of the Watch, showing the diaphragm-stylus and record-disk with relation Fig. 6 is a detached view, enlarged, showing a portion of the gearwheel carrying the stepped cam for determiningthe position of the stylus and the pinion for operating the same; and Fig. 7 is a sectional view," enlarged, showing a portion of the record-disk, its pivot, and a portion of the pointed or wedge-shaped arm for raising the record-disk into engagement with the stylus.

Referring to the letters of reference marked upon the drawings, A represents a styluslever provided with the usual stylus-points adapted to the record a, with a stout Wire B, bent in the arc of a circle and extending from one to the other of the arms of the styluslever, as shown in Fig. l of the drawings, its function being to transmit the vibrations produced by the record to the diaphragm in the Watchcase regardless of the position of the stylus.

On the shaft carrying the stylus is fixed a lever O, which rests upon and is controlled by the cam D, which determines the position of the stylus with respect to the rings upon the record-disk. This cam D is secured to a spur-wheel E, which engages a pinion V, se-

cured to the shaft which carries the minutehand of the watch, the minute-hand shaft being operated in the ordinary manner by a suitable train of gearing driven by means of a spring.

The record-disk F and its support, forming part thereof, are mounted upon a central shaft driven bya spring through the medium of a suitable train of gearing. The recorddisk is formed of hard rubber or vulcanite and contains a number of concentric rings, each provided with an undulatory surface representing sound-Waves which, through the medium of the diaphragm and stylus, call out the hour or fraction thereof corresponding to the time indicated by the hands on the dial of the watch.

The record-disk F is normally out of cngagement with the stylus, and the lever C is by preference normally disengaged from the cam D. In bringing these parts into action I provide a pivoted lever G, which has a short arm acted upon by a curved spring II, located in the edge of the watchcasing. The lever G is pivoted to a lever I, which hasa long arm guided between the pins and tapered at its end, so that by depressing the lever G against the action of the spring II the tapered end of the lever I, passed under the conical end of the support carrying the record-disk, elevates it and brings the record-diskinto engagement with the stylus. A lever J is secured to the framework of the watch by a pin which passes through a slot in the upper portion of the lever 1. One end of the lever J is forked, and between the two prongs is a pin which is socured to the lever I. From this description it will be seen that when the lever G is depressed it presses down the lever I, so that the small pin secured to the lGVGl'I acts upon the lever J and carries its forked end clownward, thus releasing the lower prong of the forked portion of the lever J from engagement with the short arm of the lever 0, bringing into play the spring K, which presses the long arm of the lever G into engagement with the cam D. lVhen the lever C is out of engagement with the cam D, said lover rests against a pin T, as shown in Fig. 2, which serves to limit the upward movement of the levers I and G.

A retaining-pawl L, which is spring-aetuated, acts upon the teeth of the spur-wheel E, which, as shown in Fig. 2 of the drawings, are pointed and known as star-teeth, and by the slight play or lost motion in the train of gears operating the spur-wheel E the pawl jumps after sufficient strain is placed upon the gear by the train from one tooth to another, thus causing the stylus to always come in perfeet alinement with the rings upon the record-disk.

Motion is imparted to the record-disk by mechanism independent of the mechanism for operating the watch. In the present instance the lower part of the record-disk F is a toothed wheel which meshes with a toothed wheel M, which in turn engages a gear-wheel mounted upon and carried by the springdrum N, which is of ordinary construction.

I prefer to wind the spring-drum operating the watch-movement and the spring-drum operatin g the record-disk by the same stem or winding device.

The stem 0, which is of ordinary construction, I provide with a bracket P, which has two arms, each of which carries a pinion It, the said bracket being held in frictional contact, so as to be caused to move either to the right or to the left with the motion of the winding-stem, this frictional contact being established by means of a screw in the stem acting against the spring washer Q, which bears against the bracket. Thus it will be seen that by turning the stem in one direction the bracket P will move and carry one of the gears It into engagement with the springdrum on one side of the stem and by a reversal of said movement the opposite gear R will be brought into action and the other of the spring-drums will be acted upon.

In Fig. 4: of the drawings I have shown the manner in which the stylus-lever A is pivoted to the support or framework U and the shaf t and minute-hand of the watch, which is provided with the usual pinion X, operated upon by the usual watch mechanism.

The sound produced by the stylus A and diaphragm Z is conveyed through an opening in the cover Y, as shown in Fig. 5. In the cover Y is also secured a leaf-spring 'W, which rests upon the edge of the record-disk and returns to its initial position after the lever Ghas been released. The watch mechanism is of the usual character, an d. the watch is provided with the usual pin S, by which means the hands of the clock may be set.

Ilaving fully described my invention, what I claim, and desire to secure by Letters latout, is

1. In combination with the mechanism of a watch or clock, a sound-reproducing machine comprising a record-disk, means for rotating the same, a diaphragm, a stylusdevcr pro vided with a stylus adapted to the record and to said diaphragm, a cam driven by the watch mechanism adapted to move the stylus and stylus-lever across the record, and means as shown for moving the record'disk into and out of engagement with the stylus.
